WeatherBug is touted as the world’s largest network of real-time weather and lightning sensors. If you want the best forecasts and the fastest alerts, Earth Networks says you should grab their free app from iTunes.
Especially now when it’s a universal build for both iPhone and iPad, and it has a Spotlight news section, 10 forecasts, thunderstorm probability in Hourly forecast, day selection buttons in the Hourly forecast, and several enhancements to make it more stable and reliable.
Earth Networks says with WeatherBug you benefit from “the fastest, most advanced early warning system, powered by the largest nationwide weather and lightning network.”
WeatherBug forecasts, radar & alerts requires the very least iOS firmware to run (6.1) and is compatible with iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation), and iPad.
